Mine mouth - Energy Education

A mine mouth electric plant is a coal burning electricity generating plant that is built close to a coal mine. In these plants, coal is excavated from the dig site, placed on a conveyor belt, and run directly into the plant where the coal will be burned. In western Canada, the main coal mines include Boundary Dam, Paintearth, Poplar River, Highvale, and Sheerness mines—which are all mine ...

A coal preparation plant takes coal from a mine and cleans it for transport. When coal comes out of a mine, it is full of impurities. These impurities lower its overall value, reduce its usefulness and increase the cost to ship it. Since impure coal is so detrimental to its use, most coal mining companies own or use a coal preparation plant.
